ANTIFREEZING PUMP.

Specification of Letters Patent. Patented J 11116 26, 1917.

Application filed October 28, 1916. Serial No. 128,270.

To all whom it may concern:

Be it known that 1, JAMES H. ALEXANDER, a citizen of the United States,residing at Conquest, in the county of Kearny and State of Kansas, haveinvented'certain new and useful Improvements in Antifreezing be operatedfrom above the surface of the.

ground, and which comprises few parts thereby enabling the same to bemanufactured economically.

In addition to the foregoing, my invention comprehends improvements inthe details of '1 construction, and arrangement of parts to behereinafter more fully described, and

particularly pointed out in the appendedclaims.

In the accompanying drawings in which similar and corresponding partsare designated by the same characters of reference throughout theseveral views in which they appear:

Figure 1, is a view in section of an antifreezing attachment,constructed after the manner of my invention, illustrating itsapplication to a pump stock, and

Fig. 2, is a transverse sectional view .taken on the line 2-2 of thepreceding figure.

With reference to the drawings, 1 indicates the body portion of myimprovement which is preferably cylindrical, and provided with a lateralextension 2 having a semi-circular recess 3 formed in its side face. Agasket 4 is disposed in the recess. The extension is flanked at eitherside by attaching lugs 5, apertured to receive bolts 6, said bolts beingadapted'to pass through ears or apertured lugs 7, formed upon a cap 8,having a semi-circular recess 9, de-

fining, with the recess 3 of the extension a circular aperture toreceive therein the pump stock of the pump as indicated at 10. Byapplying nuts 11 to the bolts 6 and tightening the same, be drawn towardeach other thereby closely shoulder 2,5.

the lugs and 7 may engaging the cap and extension 2 of the valve uponthe pump stock.

The extension 2 is formed with a passage 12 designed for communicationwith an opening 13 formed or provided in the side wall of thepump stock,the opening 12 extending into the bottom portion of the valve andintersected by an opening 14 formed in the valve at right angles to saidpassage. The opening 14 of the valve is enlarged adjacent the lower faceof the valve and internally threaded at 15 to receive a correspondinglythreaded portion 16 of a valve plug 17; The valve plug is further formedwith a rectangular portion 18 whereby it may be engaged by a wrench androtated to force the plug in place within the valve.

The valve plug 17 is further formed with a central bore 19 adapted, whenthe plug is seated within the valve body to be disposed in alinementwith the passage or opening'let of the valve body,vthe bore 19 howeverbeing slightly larger in diameter. The bore 19 of the valve plugadjacent its outer end is reduced and rounded to form a valve seat 20,and a reduced bore 21 extending therefrom.

11 valve 22 is located within the bore 19 of the valve plug, said valvebeing formed with a body portion rounded to conform to and engageupon'the valve seat 20, said valve being further provided with adepending reduced valve stem 23 which extends through the reducedopening 21. The opposite end of the body portion of the valve is formedwith a reduced shank 24L, adapted to enter and be guided forreciprocation in the recess lei of the valve, the point of connection ofsaid shank with the valve body providing a about the shank 24 anddisposed with its opposlte end engaging the shoulder 25 and the surfaceof the passage 12 adjacent its point of intersection with the recess14-. In this manner, the valve is held in close engagement with itsseat, and communication of the interior of the pump stock with theatmosphere through the valve, normally disestablished.

The under side of the valve body is formed with depending spaced ears 27adapted to support in pivotal engagement therebetween a lever 28 whichextends diametrically across the lower face of the valve plug and in aposition to engage the valve stem 23. Vertical oscillation of the leveris thus provided,

Acoil 26 is then embraced and lateral movement prevented through theagency of a guide 29 which depends from the lower face of the valvebody, and engages the lever at either side thereof. The outer terminalof the lever 28 is connected by means of a flexible element 80 to an operating means located above the surface of the ground, and not shown.

In use, the attachment is connected to the pump stock at a point belowthe frost line, and during periods of cold weather after the pump hasbeen used, the flexible element 30 is pulled upward, whereupon the valve22 is raised and disengaged from its seat, whereupon the column of waterstanding in the pump stock between the opening 13 therein and the levelof the ground is permitted to flow out through the passage 12 into thebore 19 and past the valve through the passage 21 and back into the wellor cistern.

Thus it will be seen that I have provided a simple attachment which maybe readily secured to the pump stock, and which embodies a valve andvalve seat, the parts be ing readily disassembled, and a novel means foroperating the valve.

lVhile I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations .thereovermay be made and I therefore reserve the right and privilege of changingthe form of the details of construction, or otherwise altering thearrangement of the correlated parts without departing from the spirit ofthe invention, or the scope of the appended claims.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent is 1. A pump attachment adapted to'bedetachably secured to the pump stock andhaving a passage extendingtherethrough in communication with the interior of the stock, a plugdetachably secured in the opposite end of the passage, said plug havinga valve bore and a. valve seat, a valve in said bore, means for normallyurging said valve upon its seat, and means operable from above theground level for unseating said valve to permit drainage of the waterfrom the pump stock.

2- A pump attachment adapted to be detachably secured to the pump stock,and having a passage extending therethrough, in communication at one endwith the stock, the opposite end thereof being internally threaded, avalve plug having threaded en gagement in said end of the passage, saidplug having a valve bore and a valve seat extending therethrough, avalve in said bore, a coil spring encircling the valve for retaining itupon its seat, a lever pivoted to the body portion of the attachmentadapted to engage the valve, and a flexible element extending from saidlever to the ground level whereby the valve may be unseated.

3. A pump attachment adapted to be detachably secured to the pump stockcompris ing a body portion having a passage extending therethrough incommunication at one end with the pump stock, the opposite end of thepassage being internally threaded, a valve plug having threadedengagement in said threaded end of the passage, said valve plug having abore and a reduced portion forming a valve seat, a valve movable in saidbore comprising an enlarged portion adapted to conform to and engage thevalve seat, a reduced valve stem at one end projecting beyond the plug,and a reduced shank at the opposite end, a coil spring encircling saidshank adapted to retain the valve upon its seat, a lever pivotallymounted upon the body portion and adapted to engage the stem, and aflexible element connected with the said lever and extended above theground level whereby the valve may be unseated to permit drainage ofwater from the pump stock.

In testimony whereof I afl ix my signature in presence of two witnesses.
